researching new antichagasic agents is necessary. Thus, the aim of this study is to evaluate the effect of novel chalcones and the influence of chlorine substitutions on Trypanosoma cruzi and host cells. Unsubstituted (1), 4-chlorine substituted (2) and 2,4-chlorine substituted (3) chalcones were synthesized by Claisen-Schmidt condensation, characterized, and electrical distribution was assessed by Density Fuctional
恰加斯病是一种在北美和欧洲国家出现的疾病。苯硝唑是主要药物,但在慢性期毒性大,疗效低。因此,有必要研究新的抗查气剂。因此,本研究的目的是评估新型查尔酮的作用和氯取代对克氏锥虫的影响和宿主细胞。通过Claisen-Schmidt缩合合成未取代的(1)、4-氯取代的(2)和2,4-氯取代的(3)查耳酮,通过密度泛函理论(DFT)对其进行表征,并评估其电分布。通过 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) 还原试验进行宿主细胞毒性 (LLC-MK2)。评估了对上鞭毛体(24、48 和 72小时)、锥体鞭毛体(24 小时)和无鞭毛体(24 小时)的影响。使用 7-氨基放线菌素 D (7-AAD) 和膜联蛋白-PE、二氯荧光素二乙酸酯 (DCFH-DA) 和罗丹明 123 (Rho123) 进行流式细胞术测定
